Acquiring the parts for the Duckiebot C1
✎🔗Upgrading your C0 or C0+xyz configuration to C1 starts here, with purchasing the necessary components. We provide a link to all bits and pieces that are needed to build a C1 Duckiebot, along with their price tag.
In general, keep in mind that:
- The links might expire, or the prices might vary.
- Shipping times and fees vary, and are not included in the prices shown below.
- Buying the parts for more than one Duckiebot makes each one cheaper than buying only one.
- A few components in this configuration are custom designed, and might be trickier to obtain.

LEDs
✎🔗The Duckiebot is equipped with 5 RGB LEDs. LEDs can be used to signal to other Duckiebots, or just make fancy patterns.
The pack of LEDs linked in the table above holds 10 LEDs, enough for two Duckiebots.
LED HAT
✎🔗The LED HAT (Figure 29) provides an interface for our RGB LEDs and the computational stack. This board is a daughterboard for the Adafruit 16-Channel PWM/Servo HAT, and enables connection with additional gadgets such as ADS1015 12 Bit 4 Channel ADC, Monochrome 128x32 I2C OLED graphic display, and Adafruit 9-DOF IMU Breakout - L3GD20H+LSM303. This item will require soldering to be functional.
This board is custom degined and can only be ordered in minimum runs of 3 pieces. The price scales down quickly with quantity, and lead times may be significant, so it is better to buy these boards in bulk.
PWM/Servo HAT
✎🔗The PWM/Servo HAT (Figure 30) mates to the LED HAT and provides the signals to control the LEDs, without taking computational resources away from the Rasperry Pi itself. This item will require soldering to be functional.
Male-Male Jumper Wires
✎🔗The Duckiebot needs one male-male jumper wire (Figure 31) to power the DC Stepper Motor HAT from the PWM/Servo HAT.
Female-Female Jumper Wires
✎🔗20 Female-Female Jumper Wires (Figure 32) are necessary to connect 5 LEDs to the LED HAT.
Bumpers
✎🔗These bumpers are designed to keep the LEDs in place and are therefore used only in configuration C1. They are custom designed parts, so they must be produced and cannot be bought. We used laser cutting facilities. Our design files are available [here].
